Budget estimate

$78,000,000 – $80,000,000

The budget for this project can be estimated by considering the cost of the extra work order/change order, which is $142,158.40. However, since the original contract award amount was $78,504,918.59, the total budget for the entire project would be significantly higher. Assuming the extra work order/change order is a relatively small portion of the overall project, the total budget could be in the range of $78 million to $80 million. The factors that may influence the likely payment range include the scope of work, the complexity of the project, and the materials required.
